TIRE HEAT EXCHANGE FEATURES

摘要

Provided is a pneumatic tire comprising an axis of operational rotation; a tread defining a cylindrical exterior surface extending both along and around the axis; a first sidewall defining a first sidewall exterior surface; a first shoulder region defining a first shoulder exterior surface; a heat exchange feature on the first shoulder region adapted to modify air flow over an exterior surface; a second sidewall defining a second sidewall exterior surface; a second shoulder region defining a second shoulder exterior surface; and a heat exchange feature on the second shoulder region adapted to modify air flow over an exterior surface. The heat exchange features on the first and second shoulder regions may be adapted to move air during clockwise operational rotation; or the heat exchange features on the first and second shoulder regions may be adapted to move air during counter-clockwise operational rotation.
